You can read about it in section A.5.1 of the Ada Reference
Manual (titled "Elementary Functions").

You really should learn to search the obvious sources of
information before asking questions in a news group.

True, but in fairness to the OP, the RM can be pretty inaccessible to
beginners.  However, for predefined library stuff like Sqrt, the RM is a
pretty good reference.  And Sqrt is in the index (there are actually
*two* Sqrt functions ;-) ).

For example

package Ada.Numerics.Aux;

function Sqrt (X : Double) return Double;

I don't believe that Ada.Numerics.Aux is a standard package.  It may
be provided by some implementation (I'd guess GNAT) to be used in the
implementation of the standard packages.

As Robert Dewar might say, what you believe or don't believe is 
irrelevant. What is standard is specified in the ARM. Annex A.5 
specifies package Ada.Numerics and its standard children (some optional 
children are specified in Annex G). Aux is not one of those children.

To be fair what is "obvious" to you may not be obvious to others.
Most of the books, tutorials, and websites I have referenced
since I have begun using Ada (2 years) do not spell out
any method for finding information.  They just present the
information.  In books and tutorials The RM is typically
mentioned in passing, as the justification for some piece
of syntax.  It took me a long time before I realized the
value of the RM for finding information.

Also, if you go to the AdaPower website, CLA is first on the
list of Ada reference materials.
